Tejun Heo 9b7dbc7dc0 alpha: switch to dynamic percpu allocator
Alpha implements custom SHIFT_PERCPU_PTR for modules because percpu
area can be located far away from the 4G area where the module text is
located.  The custom SHIFT_PERCPU_PTR forces GOT usage using ldq
instruction with literal relocation; however, the relocation can't be
used with dynamically allocated percpu variables.  Fortunately,
similar result can be achieved by using weak percpu variable
definitions.

This patch makes alpha use weak definitions and switch to dynamic
percpu allocator.

asm/tlbflush.h was getting linux/sched.h via asm/percpu.h which no
longer needs it.  Include linux/sched.h directly in asm/tlbflush.h.

Compile tested.  Generation of litereal relocation verified.

This patch is based on Ivan Kokshaysky's alpha percpu patch.
